IM7264C instruction manual
The Endevco 7264C is a low mass, miniature piezoresistive accelerometer. The manual outlines specific precautions for handling and mounting to avoid damage, including the use of supplied materials like Allen wrenches and flat washers. It emphasizes avoiding over-torque, which is limited to a maximum of 3.0 in-lbf (0.34 N-m), and warns against using snap-type torque wrenches.
The document provides detailed instructions for a three-step check-out process upon receipt: an impedance test, an insulation resistance test (minimum 100 megohms), and a zero measurand output test. It also covers proper mounting techniques, such as cleaning the surface and tying down the cable, and specifies a recalibration interval of 6 to 12 months depending on usage.
| Mounting Torque (Recommended) | 2.6 in-lbf (0.29 N-m) |
|---|---|
| Mounting Torque (Maximum) | 3.0 in-lbf (0.34 N-m) |
| Minimum Insulation Resistance | 100 megohms |
| Impedance Tolerance | ±25% of calibrated value |
| Recalibration Interval | 6 to 12 month intervals |
The maximum recommended mounting torque is 3.0 in-lbf (0.34 N-m).
The insulation resistance between leads/shield and case must be at least 100 megohms.
Recalibration should be performed at 6 to 12 month intervals depending on usage.
Yes, dirty units can be wiped with a damp cloth and acetone, but never soaked or immersed.
